CARBURETER.

Specification of Letters Patent.

Patented June 12, 1906.

Application iiled February 17. 1905. Serial No. 246,178.

l citizen of the United States, residing at the city of Worcester, in the county of Worcester and State of Massachusetts, have 1nvented certain new and useful Improvements in Carbureters, of which the following is a specification.

My invention relates to an improved carbureter designed for the manufacture of illuminating-gas from hydrocarbon oils and of the class of carbureters that are buried in the ground.

My invention consists of the novel construction, arrangement, and combination of parts, as hereinafter described and claimed.

In the accompanying sheet of drawings, Figure 1 represents a View, partly in section and partly in elevation, of m droyedcarbunter,... /ar'en ar e sectional 'ew on line a: a: of Fig. 1, and ig. 3 is a side elevation of the same.

Like reference characters indicate like parts.

1 designates a cylindrical tank which is supported by legs 2 2. A vent-pipe 3, which extends from the surface of the ound, is secured in the top of the tank by t eaded concap9 is arranged to c nection with an. annular flange 4, secured to said tank and surrounding a circular opening 5, formed inthe same. A conical sleeve 6 is secured to and depends from the top of the tank 1,`interiorly thereof, and in the smaller end portion of said sleeve, Which is provided with perforations 7 7, is secured the oil-fill pipe 8, Which extends within and the upper end of the vent-pipe 3. A removab ose the upper ends of the ventpipe 3 and fill-pipe 8, respectively, after the tank has been replenished with oil.

-The sleeve 6 is perforated to allow the as to escape from the tank and out throug the vent-pi e prior to refillin the tank with oil. On the ower end of the -pipe 8 is secured a bracket 10, whose outer end is bifurcated to receive the end of a swinging arm 11, which carries a ball-oat 12.

On the arm of said oat 12 is secured a circular cork disk 13, which forms a valve in closing the opening of the fill-pipe 8 when the liqulid reaches its proper leve Within the tan A pipe 14 extends above the surface of the ground and is suitably supported by the top of the tank and depends within the same, as

shown. This pipe 14 is arranged to receive air under pressure.

A carbureting-cylinder is mounted within the tank and comprises two vertically-arranged shells 15 16, concentric to each other,

and having their upper ends open and their lower ends secured to the bottom of the tank. In the shell 15 of the carbureting-cylinder near the bottom thereof is provided a circumferential row of perforations 17 17, and above these perforations between the shells of said cylinder is secured a transverse partition 18. Communication is established between the space on opposite sides of the partition 18 by means of diametrically-disposed lopenings, which are closed by cork disks 19 19.4

On each cork disk 19 is mounted a circular plate 20, which has a centrally-projecting.

stem 21 to fit loosely through each opening in the partition 18.

Two cross-arms that form a wire guard 22 overlie each valve of the carbureting-cylinder, and a space is provided between each wire guard and the top of each valve to permit the latter to rise from its seat, but not with sufficient movement as to permit the stem 21 to leave its opening in the partition 18. Thus accurate operation of each of these cork disk valves is assured.

An air-cylinder 23 is concentric with the carbureting-cylinder, extending between the shells 15 16 thereof, and said air-cylinder has a closed end which is above the open end of the shell 16 and is secured upon the depending portion of the airipe 14 within the tank. The lower portion o the air-cylinder 23 is always below the level of the liquid which passes from the tank through the perforations 17, uplifting the valves of the carbureting-cylinder and finding the same level between the shells of the same as in the tank. As the air-cylinder 23 is partially submerged in the liquid, the latter forms a seal to prevent the hydrocarbon vapor formed inthe tank from entering said air-cylinder. portion of the carbureting-cylinder forms a condensation-chamber, as at 24, and an airdischarge pipe 25 communicates with this chamber near the bottom thereof. This discharge-pipe 25 terminates at its upper por- The central l IOO tion with an integral funnel-shaped extension. l A

. ing stem'31, which is secured to the to 6, w centrally to the air- ,ipe 14, andfthis'fextension as a closed en by which said discharge-pipe 25 is supported by y said pipe 14. The conical portion of the dis 5 chargeipe 25 is so arranged to permit in forcing y the air-pressure in the pipe 14 the air moisture that ma collect upon the inner surface of this conica portion of said pipe 25 down into the condensation-chamber 24, and therebyiobtain amore 4dry air at the er portion of the shell 15 of the carbureting-cylinder prior to entering the li uid. A va oroutlet pipe 26 is secured wit in the tan y1, projecting through its bottom, where it is suitably supported, andsaid pipe 26 has a funnel-shaped mouth at its upper end.

' urrounding the outlet-pipe 26 is a collapsible vaporizer 28, com risin a bag-like structure of textile materiali, suc as burlap, and preferably constructed of a series of latring layers secured together on alternate edges constituting a succession of accordion folds.

Ratan hoops 29 29 are secured in the edges of the ring layers of burlap in such manner as to distend the same and'give a permanent shape to the bag, as will be a parent from the drawings. This collapsibib bag 28 is open at both ends and is supported by a yoke 30, properly secured to the upper ring layer of said bag and having an upwardly-extend- 'P ,0f the tank. By capillary action that portion of the bag which extends above the level ofthe liquid v1s kept constantly saturated with the liquid and offers a very extended area for the evaporation of the liquid, so that thevolatile elements quickly pass off into a gas vapor and whichfills the' up er portion within ,the tank. The vapor-outFet pipe 26 after passing through .the bottom of the tank 1 discharges into a condensing-cylinder 32, and from said cylinder 32 this vapor or gas passes through a pipe 33 to the gas-burners of a building or to a gasometer. The vaporizer 28,being of absorbent material, raises the vapor of the hydrocarbon'and holds it upon the extended portion above the liquid .until it contains a full char e in a Iquiescent state;

5o but the moment a dra t is created in the out# letipes 26 33 the hydrocarbon contained in the distended portion of the'vaporizer rapidly travels ahead'and passes throughsaid pipes 2,6 33 to'the burner, and during the time the burner illuminates the said distended portion of the vaporizer above the oil-level continues to fill with hydrocarbon. l

When the tank is to be refilled with liquid, the'cap 9 unscrewed from the pipe 3 to first allow of the escape ofwhat 'gas there would be in the tank through the perlf'lora tions of the sleeve 6 and `out through the vent-pipe 3 to the atmosphere, after"` which the spout of a common funnel is inserted in the mouth of thel fill-pipe 8 to permit the liquid to and find its proper level within the tank, as described.

When it is desired to free the bottom portion of the condensation-chamber 24 of moisture, a ump-out pipe (not shown) is inserted through) the air-inlet pipe to withdraw such moisture What I claim, and desire to secure by Letters Patent, .iS-
